CHDA
Alpha level - ANS-The degree of Type I error that is deemed perfect primarily based on
context in statistical speculation testing. See Type I blunders.
Alternative hypothesis - ANS-The complement of the null speculation this is to be tested
using the appropriate statistical test. This speculation typically calls for a few movement to
be taken.
Ambulatory payment category (APC) - ANS-The payment unit used within the medical
institution outpatient prospective charge machine (OPPS). The classification is a
resource-based totally reimbursement device.
Analysis - ANS-Reviewing and summarizing records to be used in selection making.
Analysis of variance - ANS-The statistical tool used to evaluate more than two populace
means. The null speculation exams that each one of the population means are equal.
Auditing - ANS-"The overall performance of internal and external reviews (audits) to discover
variations from mounted baselines (for example, overview of outpatient coding as compared
with CMS outpatient coding recommendations)."
Balanced layout - ANS-An experimental layout where the variety of subjects in each pattern
are the same for all populations sampled. The time period is applicable while acting an
analysis of variance or a sample t-test.
Bell curve - ANS-The form of the normal distribution. The bell pealcs at the common and
slopes down on both aspects symmetrically.
Binomial variable - ANS-"A variable that talces simplest two values (along with yes or no;
alive or dead). The opportunity of a yes or no is constant across all the subjects, and the
outcome of every subject is impartial of the others."
Case Mix Index (CMI) - ANS-"The average relative weight of all cases dealt with at a given
facility or by way of a given medical doctor, which displays the aid depth or scientific severity
of a particular institution in relation to the other groups inside the category gadget; calculated
with the aid of dividing the sum of the weights of analysis-associated businesses for
sufferers discharged at some stage in a given period through the whole variety of patients
discharged."
Centers for Medicare and Medicaid Services (CMS) - ANS-"The division of the Department
of Health and Human Services this is accountable for growing healthcare policy within the
United States, for administering the Medicare application and the federal portion of the
Medicaid program, and preserving the system part of the International Classification of
Diseases, 9th revision, Clinical Modification (ICD-9-CM) and International Classification of
, Diseases, tenth revision, Procedure Coding System (ICD-10-PCS); called the Health Care
Financing Administration (HCFA) previous to 2001."
Chi squared test - ANS-A statistical test this is used to check for relationships between
specific variables. The null speculation for this take a look at is that there may be no
affiliation between the 2 variables. Represented by way of the symbol X2 (in which X is the
Greek letter chi.)
Cluster random sampling - ANS-"The populace is split into companies earlier than the
pattern is selected. The agencies or clusters ought to be at the same time one-of-a-kind and
exhaustive. (That is, every unit within the populace is assigned to at least one and handiest
one cluster.) Clusters are then randomly decided on to make up the sample. Cluster
sampling may be accomplished as single-level or -stage."
Cluster Sampling - ANS-Sampling where population is divided into groups (or clusters);
groups are then randomly decided on to shape sample
CMS-1500 - ANS-"1. The widely wide-spread insurance claim shape advanced and
permitted by the American Medical Association (AMA) and the Centers for Medicare and
Medicaid Services (CMS) that physicians use to bill Medicare, Medicaid, and personal
insurers for expert services furnished 2. A Medicare claim form used to bill 1/3-celebration
payers for provider offerings, for instance, health practitioner office visits."
Coefficient of willpower - ANS-"A statistic that measures the amount of variance in a
dependent variable defined by one or more unbiased variables. If there's one independent
variable, then this value is the Pearson Correlation Coefficient squared."
Confidence interval - ANS-An c program languageperiod that is targeted on the pattern
estimate of a populace fee that may be calculated in order that it has a preset probability of
containing the populace fee.
Confidence stage - ANS-The opportunity that a self assurance c programming language
consists of the genuine price of a population statistic.
Contingency tables - ANS-A useful technique for displaying the connection between two
categorical variables. Each class is displayed as rows or columns. The cells within the table
constitute the matter of topics with each class attribute.
Convenience sampling - ANS-A sampling approach where the choice of units from the
population is based totally on easy availability and/or accessibility.
Correlation - ANS-A statistic this is used to describe the affiliation or courting between
non-stop variables.
Critical cost - ANS-The value that a test statistic have to be larger than to finish statistical
importance. The cost is based totally on the alpha level of the check and the distribution of
the check statistic if the null speculation is genuine.
Alpha level - ANS-The degree of Type I error that is deemed perfect primarily based on
context in statistical speculation testing. See Type I blunders.
